Objective: To investigate the effect of MEBO Scar Lotion on the recurrence of keloid after freezing. Methods: 30 patients with keloid were treated with MEBO Scar Lotion after liquid nitrogen freezing. Results: the one-year cure rate and effective rate showed that MEBO nuoping had a good effect on the prevention and treatment of cicatricial hyperplasia, and the antipruritic and anti Chuang effects were also significant. Conclusion: MEBO Scar Lotion has a good effect on the prevention and treatment of keloid growth and recurrence. liquid nitrogen tank

Since 1997, 30 cases of keloid were treated with MEBO Scar Lotion after liquid nitrogen cryosurgery, and compared with 30 cases of control group, the curative effect was satisfactory. The results are reported as follows.

1、 Materials and methods

Sixty patients with keloid were randomly divided into treatment group and control group, 30 cases in each group. In the treatment group, there were 17 males and 13 females, aged from 14 to 50 years old. There were 6 cases with diameter ≤ 1cm, 1 case with 1cm ~ 2cm and 13 cases with 2cm ~ 3cm. There were 7 cases of head and face, 16 cases of trunk and 7 cases of limbs. The condition of the control group was similar to that of the treatment group.

Two groups of patients were treated with contact freezing method: 2 minutes each time, 3 freeze-thaw cycles. In principle, the freezing depth should be 0.5cm more than the focus. Most keloids can not be cured at one time, and need to be treated once every 2 weeks, generally 2-3 times. After the scars are basically flattened, the affected areas in the treatment group were externally coated with MEBO Scar Lotion, 3 times a day for 3 months. In the control group, local changes were observed after 3 months, 6 months and 1 year, and the clinical efficacy was evaluated after 1 year.

2、 Evaluation criteria and results of coating treatment

The standard of curative effect was divided into three grades. Recovery: scar disappeared, no pain and itching, skin color returned to normal. Remarkable effect: the scar is slightly raised and thickened, slightly itchy and painful, and the skin color is basically normal. No effect: the scar recovered to the range before treatment, and the symptoms had no obvious change. The judgment results after one year are summarized in Table 1.

Table 1 shows that the cure rate of the treatment group is 86.7%. The cure rate of the control group was 43.3%, P < 0.01, there was a significant difference between the two groups. The total effective rate was 93.3% in the treatment group and 60% in the control group, P < 0.01.

3、 Discussion

The formation of keloid is not only the benign fibrous hyperplasia of skin tissue, but also the manifestation of the skin connective tissue responding to trauma beyond the normal range. These patients often have scar quality, after trauma or mechanical stimulation, local inflammation occurs and fibrous hyperplasia is formed. Although there are many treatments for this disease, they are not ideal. For example, liquid nitrogen cryotherapy is effective for some patients, but it can recur quickly after operation. In order to solve the problem of recurrence after cryotherapy, 30 cases of keloid were treated with liquid nitrogen freezing plus MEBO Scar Lotion. The effective rate and cure rate of the treatment group were significantly higher than those of the control group.

According to clinical observation, keloid is easily irritated and hypersensitive, and even clothing compression can cause itching symptoms. If the patient is scratched because of itching, it will further promote the hyperplasia of scar, which is an important reason for the recurrence of the disease. MEBO Scar Lotion is mainly refined from all natural ingredients such as linoleic acid, tyramine, sesamin, cactus essence, beeswax and other natural ingredients. It can moisturize the skin, protect the skin, relieve itching, relieve pain and inhibit the proliferation of fibrous tissue. In addition, it can improve the hypoxia condition of microvessels and peripheral nerve endings in scar tissue and prevent scar tissue hyperplasia. liquid nitrogen tank
